I use scp to transfer files between two linux servers and here's how I use it.
scp <i>filename</i> <i>user</i>@<i>server_addr</i>:<i>location</i>
Don't ask, I'm not a linux expert. For more info you can type the following at the command line:
scp --man:
scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program][[user@]host1:]file1 [...] [[user@]host2:]file2
